In the DNS status codes are called rcodes and it's slightly harder to return the correct
answer in case of failure.
So CoreDNS treats only SERVFAIL (dns.RcodeServerFailure) as special and will then assume
nothing has written to the client. In all other cases it is assume something has been written
to the client.
So CoreDNS treats
* SERVFAIL (dns.RcodeServerFailure)
* REFUSED (dns.RecodeRefused)
* FORMERR (dns.RcodeFormatError)
* NOTIMP (dns.RcodeNotImplemented)
as special and will then assume nothing has written to the client. In all other cases it is assume
something has been written to the client.
